Effective fruit fly control requires an integrated pest management approach which may include the use of area-wide sterile insect technique (SIT). For SIT to be cost-effective, the density of the wild population needs to be at low levels prior to the release of sterile insects. The required population level is achieved by the utilization of population suppression methods. This may include: insecticide-baits, bait stations, orchard sanitation practices and biocontrol agents including entomopathogens microorganisms. This manual is aimed at contributing the use of sterile flies as vectors of conidia of entomopathogenic fungi, for fruit fly suppression in operational programmes, as well as the so-called disseminator devices of conidia of entomopathogenic fungi. This document presents a review of different studies that support the use of entomopathogenic fungi to suppress fruit fly populations. It describes the process to characterize pathogenic fungi strains, sterile fly the inoculation process, handling of sterile flies used as vectors, biosecurity recommendations and release densities of inoculated sterile flies, as well as the density of the disseminator devices. The integrated use of the SIT and Microbial Control (MC) as components of area-wide management strategies is presented. The FAO/IAEA Officer responsible for the publication was Walther R.
